Objective: To work out a Parent-Adolescent Conflict Resolution Questionnaire with Chinese culture and explore its validity and reliability. Methods: The original items were selected based on the opening investigation on 548 adolescents and discussion with some parents and professionals, in the next step, 914 adolescents were recruited to test the reliability and validity. Results: The distribution of factors confirmed the theoretical structure. The alpha coefficient ranged from 0. 56 ~ 0. 86, retest coefficient after a month were 0. 67 ~ 0. 88 ( P

Objective To assess value and limitations of non-invasive methods in assessing liver fibrosis.Methods By summarized current situation and advancement of serum fibrotic markers,ultrasound,CT and MRI in assessing liver fibrosis,we investigated their value and limitations.Results In addition to diagnosis,non-invasive methods of assessing liver fibrosis assess severity of liver fibrosis.For liver fibrosis,however,non-invasive methods can not monitor effectively reaction to therapy and progression.Conclusion Non-invasive methods play important roles in diagnosis and assessing severity of liver fibrosis,and reduce the need of liver biopsy.

Objective To probe CT grading criteria of vascular invasion in pancreatic cancer.Methods Retrieved articles in CNKI and PubMed about value of CT in preoperative assessment of vascular invasion in pancreatic cancer last ten years.Results Multislice helical CT is considered the best imaging method to assess the invaded peripancreatic vessels in pancreatic cancer.There are different CT criteria of vascular invasion in pancreatic cancer based on extension of hypodense tumor and its relation to blood vessels,on the degree of circumferential contiguity of tumor to vessel,on the degree of lumen stenosis,and on the degree of contiguity between tumor and vessels combined vascular caliber.Conclusion CT grading criteria are not uniform,each one has defects.

Objective To investigate the diagnostic value of a double action MR contrast agent——gadobenate dimeglumine (Gd-BOPTA) for focal liver lesion and biliary system disease.Methods Articles about Gd-BOPTA in CNKI and PubMed for the past few years were searched and the value of Gd-BOPTA in the diagnosis of focal liver lesion and biliary system disease was summarized.Results For focal liver lesion,Gd-BOPTA not only can reveal blood supply of the lesion,but also reveal the hepatocellular functional status in the lesion.For biliary system,biliary excretion of Gd-BOPTA can be used to evaluate the anatomic structure of bile duct,function of gallbladder and biliary system disease.Conclusions Gd-BOPTA has an important value in the diagnosis of focal liver lesion and biliary system disease.Gd-BOPTA may have wider applications in the future.

Objective To introduce the current value of multi-detector row CT (MDCT) and magnetic resonance imaging (MRI) techniques on evaluation of diffuse hepatic parenchymal diseases. Methods By literature review,the application and recent advances of various kinds of MDCT and MR imaging techniques in evaluating diffuse hepatic parenchymal diseases were summarized. Results There were three kinds of diffuse liver parenchyma diseases,which were the diseases of storage,vascular and inflammatory. The morphology changes of diffuse liver parenchyma diseases could be demonstrated well by MDCT. MRI,especially MR functional imaging could reflect the morphology changes,and cellular metabolic activity of the liver,which provided qualitative and quantitative information for the diagnosis and evaluation of therapeutic effect on diffuse liver parenchyma diseases. Conclusion MR imaging techniques,especially those functional techniques,developed rapidly and had practical value in both the diagnosis and severity assessment of hepatic fibrosis.

Objective To explore the relationship between the family conditions and internet addiction of medical college students with limb disabled. Methods 400 medical college students were investigated by the University Student Going-online Investigation table, EMBU and Chinese Internet Addiction Scale. Results There was significant correlation between parental occupations and internet addiction total score of medical college students with limb disabled( r= 0.195, P < 0.01 ; r = 0.163, P < 0.05 ). There was significant correlation and prediction between negative parental rearing patterns such as the parents' punishment-severity and rejection-denying and dimensions of interpersonal relations, health, forced going-online behaviors, time management( P < 0.05, P< 0.01 ), but there was no significant correlation and prediction between parents' warmth-comprehension and all dimensions. Conclusion Family conditions play a important role in influencing internet addiction of medical college students with limb disabled.

Objective To investigate the imaging features of Budd-Chiari syndrome(BCS) on 64 slice spiral computed tomography(64SCT) and the diagnostic value of 64SCT for BCS.Methods Twenty-nine patients diagnosed as BCS by 64SCT were retrospectively included into this study and all the patients were researched by digital substraction angiography(DSA).Two abdominal radiologists analyzed the CT imaging features of BCS,paying attention to the vascular lesion,the morphology abnormality of the liver and the degree of portal hypertension,with review of DSA findings.Results ①The accuracy of 64SCT for BCS was 93.1%(27/29),and there were 2 false positive cases and no false negative case.The accuracy of 64SCT for those patients with thrombosis of inferior vena cava(IVC) and(or) hepatic vein(HV) was high as compared to those with stenosis of IVC and(or) HV.②The morphology abnormality of the liver included hepatomegaly(24 cases),low attenuation(27 cases) and inhomogeneous pattern of parenchymal contrast enhancement(5 patients in arterial phase and 19 patients in portal vein phase).③The images of all the patients showed the features of portal hypertension.Conclusion The accuracy of 64SCT for BCS is satisfactory and the false negative is seldom.The 64SCT could accurately display the morphology abnormality of the liver and the compensatory circulation in BCS patients.For those patients with stenosis of IVC and(or) HV,however,the diagnostic power of 64SCT is limited.

0.05).For following indexes: whether or not having intussusception,the location of intussusception,finding reason caused intussusception,the confidence index of the doctor between original image add MPR image group and original image group had significant difference(5.00 vs.4.24,4.76 vs.4.29,4.29 vs.3.71),and the confidence index of the doctor of original image add MPR image group exceeded that of original image group(P

Objective: To explore the structural relationship of social support,loneliness and internet addiction tendency.Methods: Questionnaires were used to investigate 355 college students.Results: The internet addiction tendency of college students had significant negative correlation with social support total scores and subjective social support,and positive correlation with the total scores and every dimensions of loneliness;college students’ social support had significant negative predictive effect on internet addiction tendency;loneliness of college student played a completely mediating role between social support and internet addiction tendency.Conclusion: Loneliness of college students plays a completely mediating role between social support and internet addiction tendency.

Objective To observe level of thyroid and corticosteroid hormone of peacekeepers in South Sudan the harsh environment under stress and explore the changes of hormone and its related causes the body to suffer stress.Methods 25 peacekeepers were drawn blood before going abroad,after going abroad 1 months,4 months and 7 months,respectively.Methods of immune by magnetic separation were adopted and determined the changes of thyroid hormone and cortisol levels.They were compared with before going abroad.Results After going abroad 1 months T3 (1.780 ±0.345)ng/mL,T4 (88.609 ±14.486)ng/mL,FT3 (3.758 ±4.287)pg/mL,FT4 (15.152 ±6.422)pg/mL than before going abroad (1.458 ±0.206)ng/mL,(2.060 ±0.642)ng/mL,(11.672 ±3.627)pg/mL,(96.958 ± 12.286)pg/mL were significantly increased (t =3.670,2.410,2.019,2.798,all P <0.0 ).TSH (1.320 ± 0.518)μIU /mL after going abroad 4 months was lower than before going abroad(1.872 ±0.821)μIU /mL decreased significantly(t =3.175,P <0.05).Conclusion In the role of the environment change of stress factors,changes of thyroid hormone and cortisol levels of body were obvious.We suggest to make countermeasure as soon as possible and appropriate intervention.At the same time the peacekeepers are detected comprehensive hormone detection and psy-chological counseling before going abroad,it is significant for the successful completion of peace -keeping task.
